Ablation of the Id2 Gene Results in Altered Circadian Feeding Behavior, and Sex-Specific Enhancement of Insulin Sensitivity and Elevated Glucose Uptake in Skeletal Muscle and Brown Adipose Tissue
A) Representative images of hematoxylin/eosin stained gonadal white adipose tissue sections of male and female WT and Id2−/− mice (scale bar = 50 µm). B) Cell area of gonadal WAT in WT and Id2−/− mice (ANOVA: genotype, P<0.05; sex, n.s.; interaction, P<0.001). No significant correlation was detected between cell size and age of animal (Spearman’s rank order correlation/linear regression, n.s.).
